This is appalling... check out the REALLY bad retouching here...
There is no way a lettering artist or signmaker did this!
Compare the thin A of Armstrong and I of Siddeley with the blobby M and G of Armstrong
And check out all the strange Rs, and that extra bold E in Siddeley. UGH!
What is the point of retouching something so badly? especially when the company no longer exists.
The retouched Flegg saddles sign in Shelton Street is appalling too... they've used what looks like gloss or satin paint on that one... they should have just left the orignials to fade
